I couldn't believe it when I saw the Infragistics tutorial on this forum (after spending hours on the infragistics forums). I have one small question.

I'm able to bind an ES collection to the ultra grid when there is at least one entity in it. However when the collection is empty the grid behaves very strangely. It basically only lets me add one item and then locks up. Is anybody else seeing this behavior?

We are adding a fix for this, if your grid is empty just do this (temporarily)

myCollection.AddNew();
myCollection[0].MarkAsDeleted();

Great news. Can you tell me which build number this first appeared in?

Very good. I'm putting a call to that method in the parameterless constructor of my CollectionBase - custom base class. Do you see any problem with that? Seems to work so far.
